EPHRAIM S. MORTON, OF BROGKTON, MASSACHUSETTS.

SASHFASTENER.

SPECIFICATION forming part of Letters Patent No. 255,003, dated March 14,1882. Application led November 7, 1831. (Model.)

To all whom it may concern: y

Beit known that I, EPHRAIM S. MoRroN, of Brockton,in the county ot Plymouth and State of Massachusetts, have invented certain Improvements in Sash-Fasteners, otl which the following is a specification.

This invention has for its object to provide a sash-fastener comprising two spring-impeded bolts or catches, each arranged to fasten a different sash and adapted to be operated independently ot' each other, and to be locked or made rigid either when both are projected to fasten their sashes or when both are retracted, so as to be inoperative, the means employed for locking the bolts being such that a special key is required to unlock the bolts, so that when the sashes are locked theyeannot be unlocked, except by the use of said key.

To these ends my invention consists in the improved'sash-astener which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part ot' this specilication, Figure lrrepresents, in dotted lines, a view of the outer side ot1 a sash-fastener embodying my invention applied to a window-easing. Fig. 2 represents a view of the inner side ot the fastener detached. Figs. 3, 4, and 5 represent respectively sections on lines l 1, 2 2, and 3 3 ot1 Fig. 2. Fig. 6 iepresents a view ot' the rear side otl the fastener with both bolts projected and locked. Figs. 7, 8, and 9 represent respectively sections ou lines 4 4, 5 5, and 6 6 ot' Fig. 10. Fig. l0 represents a view ot1 the rear side of the fastening with both bolts retracted and locked. Fig. 1l represents a section on line 7 7 of Fig. 6. Fig. 12 represents a longitudinal section on line S S of Fig.10. Fig. 13 isasection on line 9 9 of Fig. 12.

The same letters of reference indicate the same parts in all the ligures.

In the drawings, A represents a supportingplate, adapted to be secured to a window-casing.

B C represent the catches or boits,'which are adapted to slide in apertures in the. plate A,

and to secure respectively the upper and lowerV sash by entering holes formed in the edges ot' said sashes. Said bolts are pressed outwardly in position to secure the sashes by springs D D bearing on their innerends, said springs being preferably the ends ot' a single spiral spring,

as shown in Fig. 2, and rest in grooves formed in the ends of the bolts.

The outer bolt, B, which secures the upper sash, is retracted against the force ot' its spring by an operating device composed ot a rod, E, journaled in ears on the plate A, and an arm, F, secured to said rod by means of a feather, Gr, so that the rotation of the rod will swing the arm. while the lengthwise movement of the rod will not aft'ect the arm, the rod sliding through the arnnwhich is prevented from moving with the arm when the latter moves endwise by stops on each side. The arm F projects at its outer end into a groove formed in the side ot' the bolt B, so that when the rod E is turned in its bearings and the arm F is swung thereby in the directionindicated by the arrow in Fig. 3 the bolt B will be retracted and caused to release its sash. The rod E projects through the window-casing into the room, and is provided with a handle, by which it is operated.

The inner bolt, G, which secures the lower sash, is retracted by an operating device which is normally independent ofthe rod E, and consists of a sleeve, H,journaled on said rod so as to turn independently thereon, and provided with a rigidly-attached arm, I, projecting into a groove in the bolt C. J represents another arm, rigidly attached to the sleeve H, and pro` jecting into a groove in a push-pin, K, which passes through the plate A, and is adapted to be pressed inwardly by a person Within the room, and thus turn the sleeve Hand cause the arm I of the latter to retract the bolt (l. It will be seen, therefore, that the bolts B C are adapted to bo operated independently.

The operating-rod E is provided with a lug, L, near one end of the sleeve H, and the sleeve is provided with two notches,M N, each adapted to receivethe lug L when the rod lil is moved end wise, so as to force thelu gtoward the sleeve, the sleeve being prevented from end wise movement by suitable stops. When the lug L is pushed into either notch the sleeve is made rigid upon the rod E, so that the bolts B C cannot move independently. I provide a locking device `to prevent the rod E from turning or moving endwise when its lug is engaged with the sleeve, said device consisting ot a springbolt or tongue, O, secured to .the plate A, and

IOO

adapted to spring into an orifice in the rod E when the latter is moved to cause its lug to enter one of said slots. When the tongue O is in the orifice ot' the rod the latter is held thereby from moving in any direction, and can only be released by inserting in the end of the rod E, which is hollow, a key, P, adapted, when rotated in the rod, to force the tongue O out of the orifice thereof. The slot M is so located that the lug L can be pushed into it only when the bolts B C are projected, and the slot N is so located that the lug L can be pushed into it only when the bolts are retracted. The bolts can therefore be locked and made rigid when projected, and thus caused to lock the sashes, so that they cannot be unlocked without the employment. of the key P. The bolts can also be locked when retracted, so that the sashes can be moved freely without reference to the bolts.

The key P has au eccentric teat, U, on its end, which enters aneceentric hole formed in the inner end of the cavity of the rod E, so that the key will rotate eccentrically iu the rod. The same spring that forces the bolts B (l outwardly also presses the rod E outwardly .after it is unlocked by the key P.

I elaimi l. In a window-sash fastener, the combination of two spring-impeded bolts or catches supported on a suitable plate on the windowcasing, each arranged to fasten a diit'erent sash, ajournaled operating-rod having au arm adapted to retract the inner bolt when said rod is rotated, an operating-sleeve journaled on said rod and provided with an arm adapted to retract the outer bolt when said sleeve is rotated, and means for rotating said sleeve independently of the rod, as set forth.

2. In a window-sash fastener, the combination of two spring-impelled bolts or catches supported on a suitable plate on the windoweasing, each arranged to fasten a di'erent sash, and each provided with devices, substantially such as herein described, whereby they may be operated independently, and means, substantially such as herein described, for locking said operating devices and. bolts either when the latter are projected so as to lock the sashes or retracted so as to be inoperative, as set forth.

3. In a window-sash fastener, the combination of two spring-impelled bolts or catches supported on a suitable plate on the window casing, a journaled operating-rod having an arm engaged with the inner bolt, the rod being adapted both to swing said arm and to move length-wise independently thereof, an operating-sleeve journaled on said rod and provided with an arm engaged with the inner bolt, said sleeve being adapted to rotate with the rod, but prevented from moving endwise, a lug on the rod adapted by an endwise movement ot the rod to enter either of two notches formed in the sleeve, and a locking device, substantially such as herein described, to prevent the operating-rod from rotating when its lug is engaged with either of the notches of the sleeve,

thereby causing the operating-rod to hold both bolts either projected or retracted, as set for th.

4. The operating-bolt having a longitudinal key-hole and a lateral slot or opening, combined with a spring locking bolt or tongue adapted to project into said keyhole, and a key adapted to be inserted in the inner end of the operating-rod and disengage the locking-bolt therefrom, as set forth.

In testimony whereofI have signedmy name to this specification, in the presence of two subscribing witnesses, this 12th day of October, A. D. 1881.
